Something I was thinking about last time but forgot in the midst of melodrama was that there are certain exercises which might save your life if you are proficient in them.
The three that come to mind are swimming, running, and climbing. I think that swimming is pretty obvious, although it is less important in totally landlocked or frozen areas. I always thought swimming was really good exercise as well. As to running, it never hurts to be able to get far the hell away from something as fast as possible. And with climbing the main idea is being able to lift your body up over a ledge that you are clinging to “for dear life”. I think that drowning and falling are still relatively common ways to die and perhaps if you are better at swimming and climbing you won’t die that way, or you will avoid more serious injuries perhaps.
Honestly I was initially thinking chin-ups which I am now unable to do rather than climbing (which I also am unlikely to be able to do anymore but it doesn’t come up much in the city), and there is some transfer as far as muscular training goes. And a fire escape is more similar to a chin-up bar than a mountain face but nonetheless. if you can go from clinging with your finger tips to hoisting yourself over something then you will be in ideal upper body condition. I bet guys who can do that can lift over 100 kilos, at least 50 for women.
If you want to be able to save someone else’s life then being able to carry weight equivalent to a person for a certain distance is probably the main thing, followed by being able to lift heavy mass off people. In theory with the right locations and levers and sleds you can make up for physical strength with physics but in reality you will often find yourself lacking for a good lever at the scene of a car crash or avalanche.
When did I become a survivalist? Who the hell knows but I’ve made it this far.
